Abstract
La presente invención se refiere a un cinescopio de color que incluye una mascarilla de sombra montada adyacente a una pantalla de línea catodoluminiscente; caracterizado porque la mascarilla de sombra incluye una pluralidad de aberturas en forma de ranura, ubicadas en columnas; teniendo la mascarilla de sombra una periferia sustancialmente un tanto rectangular con dos lados largos opuestos y dos lados cortos opuestos; un eje mayor (X-X) de la mascarilla es un eje que pasa a través del centro de la mascarilla y que se extiende centralmente a través de los lados cortos, y un eje menor (Y-Y) de la mascarilla que es un eje que pasa a través del centro de la mascarilla y que se extiende centralmente a través de los lados largos; y las columnas de aberturas se extienden generalmente en la direción del eje menor y están separadas entre sí en la dirección del eje mayor; caracterizado porque la separación (A(H) de columna a columna de aberturas, cerca del eje menor de la mascarilla, es menor en los lados largos de la mascarilla que cerca del eje mayor de la misma.The present invention relates to a color kinescope including a mounted shadow mask adjacent to a cathodoluminescent line display; characterized in that the shadow mask includes a plurality of slot-shaped openings, located in columns; the shadow mask having a substantially somewhat rectangular periphery with two opposite long sides and two opposite short sides; a major axis (XX) of the mask is an axis that passes through the center of the mask and extends centrally through the short sides, and a minor axis (YY) of the mask that is an axis that passes to through the center of the mask and extending centrally through the long sides; and the columns of apertures generally extend in the direction of the minor axis and are spaced apart from each other in the direction of the major axis; characterized in that the separation (A (H) from column to column of openings, near the minor axis of the mask, is less on the long sides of the mask than near the major axis of the mask.
